Abstract
Abstract A contact lens applicator that provides a deformable, resilient transparent, cup, the edge of which when compressed and applied to tissues surrounding the eye, spreads them, so that the eye is widely exposed for the application of a contact lens, and the cup of which is transparent so that the user, with the aid of a mirror can exactly guide the lens to exact seating on the iris.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
127 words
A contact lens applicator: a. a resilient, transparent, compressible cup with a normally oval opening having a general dimension larger than a widely open eye, b. a generally central tubular enlargement in the bottom of the cup, c. a tube frictionally seated in the tubular enlargement and extending at one end into the cup, and at the other end outside the cup, d. a tubular conduit in the tube, e. a seat for a contact lens in the cup and attached to the top of the conduit, f. an annular seat in the tube, g. a light spring in the tube engaged with the seat for the contact lens and with the annular seat, whereby the contact lens seat is yieldable to light contact with the eyeball.
Claim 2
Dependent Claim
127 words
A contact lens applicator: a. a resilient, transparent, compressible cup with a normally oval opening having a general dimension larger than a widely open eye, b. a generally central tubular enlargement in the bottom of the cup, c. a tube frictionally seated in the tubular enlargement and extending at one end into the cup, and at the other end outside the cup, d. a tubular conduit in the tube, e. a seat for a contact lens in the cup and attached to the top of the conduit, f. an annular seat in the tube, g. a light spring in the tube engaged with the seat for the contact lens and with the annular seat, whereby the contact lens seat is yieldable to light contact with the eyeball.
Claim 3
Dependent Claim
44 words
The device according to claim 1 and a. a passage in the seat for the contact lens communicating with the tubular conduit, whereby contact lens fluid applied to the bottom of the conduit may flow through it onto the seat for the contact lens.
Claim 4
Dependent Claim
21 words
The device according to claim 2 and a. a passage in the cup for the introduction of an eye irrigating fluid.
Claim 5
Dependent Claim
21 words
The device according to claim 1 and a. a passage in the cup for the introduction of an eye irrigating fluid.
Claim 6
Dependent Claim
20 words
The device according to claim 1 and a. a rim of soft material attached to the edge of the cup.
Claim 7
Dependent Claim
45 words
The device according to claim 1 and a. the tube frictionally seated in the tubular enlargement, adjustable to bring the position of the contact lens seat in the cup from a position further away, to a position close to the cup edge of the cup.
Claim 8
Dependent Claim
230 words
A contact lens applicator comprising: a. a resilient, transparent, compressible cup with a normally oval opening having a general dimension larger than a widely open eye, b. a generally central tubular enlargement in the bottom of the cup, c. a tube frictionally seated in the tubular enlargement and extending at one end into the cup, and at the other end outside the cup, d. a tubular conduit in the tube, e. a seat for a contact lens in the cup and attached to the top of the tube, f. an annular seat in the conduit, g. a light spring in the tube engaged with the seat for the contact lens and with the annular seat, whereby the contact lens seat is yieldable to light contact with the eyeball, h. a passage in the seat for the contact lens communicating with the tubular conduit, whereby contact lens fluid applied to the bottom of the conduit may flow through it onto the seat for the contact lens, i. a passage in the cup for the introduction of an eye irrigating fluid, j. a rim of soft material attached to the edge of the cup, k. the tube frictionally seated in the tubular enlargement, adjustable to bring the position of the contact lens seat in the cup from a position further away, to a position close to the cup edge of the cup.
Claim 9
Dependent Claim
230 words
